Area Replacement Method: The traditional area-replacement method has been used in ASME pressure vessel and piping codes for many years. The area-replacement concept requires that the metal removed to make an opening be replaced by an equal area of reinforcement within a prescribed region around the opening.
除管壳式换热器热器之整体式壳體内的材料外,管板或扁平封头中之任何材料均不应被视为对相邻壳体或封头中之开孔能起补强作用。
請將如下條款修定為:
(e) With the exception of studding outlet type flanges and the straight hubs of forged nozzle flanges [see UG-44(a)(10)], bolted flange material within the limits of reinforcement shall not be considered to have reinforcing value. With the exception of material within an integral hub, no material in a tubesheet or flat head shall be credited as reinforcement for an opening in an adjacent shell or head.除用双头螺栓连接之出口型法兰和锻造管嘴法兰的直颈[参见 UG-44(a)(10)]外,在补强范围内的螺栓法兰材料不应被认为具有补强值。 除了管板延伸兼作法兰或管板与封头形成整体式管箱的材料外,管板或扁平封头中之任何材料均不应被视为对相邻壳体或封头中之开孔能起补强作用。
如此一來,前後句子才有相關性性
